Sodium trioxodinitrate's (Na2N2O3, Angeli's salt) unique cardiovascular effects have been associated with its ability to yield HNO upon dissociation under physiological conditions. Due to its potential applications in new therapies for heart failure, the dissociation of Angeli's salt has recently received increased attention. The decomposition mechanism has been previously studied by quantum mechanical methods using a continuum approximation (PCM) for the solvent effects. In this work we use our...
